        These are some common issues that you should be aware of. If you're having trouble, you may want to look through these to see
        if any apply to you or may be the source of your problem.

    <p>
        <b>Annotations aren't saved when running locally in Mozilla Firefox</b><br />
        The solution here is to run the graphs using a web server. At this time (March 2010) only Safari 4, Chrome 4 and Opera 10.5
        support saving annotations when running locally.
    </p>

    <p>
        <b>Missing text in Google Chrome</b><br />
        Since one of the dev releases there has been an issue with Google Chrome 4 and 5, asynchronous processing and  not rendering
        graph labels. This has been remedied by asimply not using asynchronous processing. Because of the tag placement on the front page,
        the effect shouldn't be apparent. Other browsers (eg Firefox, Safari, Opera, MSIE) are fine.
